I will keep a closer eye on this thread guys. Epic, I'm not 100% sure about your temps - I wish I had paid more attention to my temps with my shuttle but it certainly doesnt seem right - I think you need to get a proper temp diode on there. Have you updated your bios at all recently? It's not right mate.

The ST and Mach II models are almost identical - apart from the USB and the electronics, the cooling potential of both units are more or less the same.

Obviously the cpu temp will rise under load, but it isnt as drastic as it is with air. It also depends on your particular chip and how hot it runs. Every chip is different, remember that.

With my P4 3.0C idle actual (ie the cpu actual) is -35, the evaporator temp is -50 and the reported cpu temp is -45.

warlord, wot mobo you got, is it an abit? ive heard they are a bit inacurate with their temp reading (wether this is fact or not i dunno) but the -29 mbm shows seems more feasable, i never pay much attention to wot the mobo says

hmmmmz the slight high idle temp iw ould of just put down to the case/mobo probably as im unsure of how efficent the shuttls cooling is, judging by the ammount of freinds of mine that have blown their gfx cards in these machines id say not good :P

But the -1 to 0 at load def seems wrong and i really dont know what to suggest ... sorry epic

Epic, its prolly a good mobo, but like all small things there are sacrifices, a small case is gonna have a higher temp within the case, but i still dont think this would be enuff to make the temp rise quite so much.
